Scalability cabling The verification checklist for the scalability ports is described in the following list. Note: The "Connected to" information is not known for ports that had been connected to the other server prior to booting as a standalone server for the diagnostic programs. 1. The "Connected to" column must be "unknown" for four ports, as shown. 2. The "Connected to" column must show that both "P3"s connect to each other. 3. The "Is Ready" just be "Yes" for all six ports. 4. The "Has Cable" must be "Yes" for all six ports. 5. The "Transmit" and "Receive" errors should both be "No" for all six ports. After performing these checks for one server in the configuration, perform the checks for the other server. The results must be identical. RXE cabling The cabling to an RXE100 Expansion Enclosure should be as follows: Primary Port A to Secondary Port A Primary Port B to RXE100 Side A Secondary Port B to RXE100 Side B These connections can be verified with the following display (from the diagnostic program main menu, select ″Hardware Info″ and ″Summit Chips″). The primary display in the following example begins with ″Memory″: This_______ Connectd_to Ext Is Has Port Trans Recei Error no Chip_._Port Chip_._Port Int Ready Cable Speed Error Error Count Memory: 07 Memory_1.P0 PCI-X__1.P0 Int yes yes 1000 MHz no no 00 08 Memory_1.P1 PCI-X__2.P0 Int yes yes 500 MHz no no 00 09 Memory_2.P0 PCI-X__2.P1 Int yes yes 500 MHz no no 00 10 Memory_2.PB RXE100_A.PA Ext yes yes 500 MHz no no 00 PCI-X: 11 PCI-X__1.P0 Memory_1.P0 Int yes yes 1000 MHz no no 00 12 PCI-X__1.PA Ext yes yes 250 MHz no no 00 13 PCI-X__2.P0 Memory_1.P1 Int yes yes 500 MHz no no 00 14 PCI-X__2.P1 Memory_2.P0 Int yes yes 500 MHz no no 00 RXE100: 15 RXE100_A.PA Memory_2.PB Ext yes yes 500 MHz no no 00 16 RXE100_A.P1 Int yes yes 250 MHz no no 00 In line number 12, Port A is shown as ″Ready″, but the ″Connected_to″ is unknown. In line number 10, Port B is shown as ″Connected_to″ RXE100 Side A, Port A. In line number 16, Port 1 is the internal port connecting to Side B, and it is ″Ready″. Chapter 3. Diagnostics 73
